Ammonia is in high demand and widely used, yet its production still predominantly relies on the energy-intensive Haber–Bosch process, highlighting the urgent need for a milder alternative technology. Photocatalytic N2 fixation shows great promise in this regard despite the challenge of developing high-efficiency catalysts. In this study, we successfully prepared micronano spherical Bi2MoO6/Bi2MoO6–x S-Scheme homojunctions using a simple solvothermal-calcination coupling method, which offer unique advantages for nitrogen fixation catalysis: (i) the micronano structure mitigates the agglomeration issue common in nanomaterials, thereby exposing more active sites; (ii) the in situ constructed S-Scheme homojunction features a high-quality surface and interface structure, enhancing the spatial separation and transport of photogenerated charges and preserving strong redox capabilities; and (iii) the oxygen-rich vacancy structure promotes the N2 adsorption and activation. Thanks to those favorable properties, the Bi2MoO6/Bi2MoO6–x (BMO/BMOOV) S-Scheme homojunction demonstrates exceptional ammonia production efficiency, with a NH4+ generation rate of 238.7 μmol g–1 h–1 under simulated sunlight, which is over 5.2 times higher than that of pristine Bi2MoO6 (BMO) and significantly outperforms other reported similar catalytic systems (see Table S1). This work introduces a simple and versatile method for synthesizing homojunctions, potentially inspiring the development of more efficient photocatalysts for nitrogen fixation and beyond.

For ultimate photocatalytic CO 2 reduction efficiency, In 2 O 3 synthesized via co-precipitation/calcination was architecturally integrated with Bi 2 MoO 6 through solvothermal assembly, constructing composite catalysts. In 2 O 3 incorporation triggered absorption edge red-shifting, quenched photoluminescence, and amplified photocurrent density. The 2 %-In 2 O 3 composite delivered 12.5 μmol/g/h CO yield under 300W xenon lamp – achieving a 2.5-fold enhancement versus pure In 2 O 3 and a 1.8-fold gain relative to pure Bi 2 MoO 6 . This superiority arose from heterostructuring induced by In 2 O 3 loading, which expedited photogenerated carrier mobility and elevated CO 2 conversion activity.

For the purpose of further improve the efficiency of photocatalytic CO 2 reduction and realize cascade utilization of the full solar spectrum, Bi 2 MoO 6 quantum dots were in situ deposited on the surface of carbonized pomelo peel (CPP) to form Bi 2 MoO 6 @CPP 0D/3D heterojunction catalyst. With a diameter of less than 10 nm, the quantum-limited field effects confirm the successful construction of Bi 2 MoO 6 quantum dot. The band structure of Bi 2 MoO 6 @CPP 0D/3D is beneficial heterojunction , which is able to utilize not only the UV–Vis band to generate photogenerated carriers that reduce CO 2 to CO mainly, but also the IR band of the solar spectrum to increase the temperature of photothermal catalytic reaction. The experiment indicated that the photogenerated electrons generated by Bi 2 MoO 6 @CPP 0D/3D heterojunction catalysts flowed through the interface C-O-Bi bridge and migrated to the surface of CPP, forming an electron interface. The interface C-O-Bi electron bridge enhanced the separation ability of photogenerated carriers, thereby increasing the CO yield to 50.77 μmol/(g·h). Further experiment showed that the oxygen-containing groups’ concentration of CPP were ameliorated by thermal activation and acid-base activation, which increased the concentration of interface C-O-Bi electron bridge between Bi 2 MoO 6 and CPP, finally promoting the CO yield to 66.94 μmol/(g·h), which is 12.3 times greater than that of bulk Bi 2 MoO 6 .

Photocatalytic materials can be used as self-cleaning functional materials to alleviate the irreversible fouling of ultrafiltration membranes. In this work, the small size g-C 3 N 4 /Bi 2 MoO 6 (SCB) blended polysulfone (PSF) ultrafiltration membranes was fabricated by hydrothermal and phase inversion methods. As a functional filler of ultrafiltration membranes, the small size g-C 3 N 4 nanosheet decorated on the surface of Bi 2 MoO 6 can enhance the photocatalytic performance for bovine serum albumin (BSA) degradation, and remove irreversible fouling under visible light irradiation . In addition, the introduction of SCB microspheres into PSF matrix obviously increased the porosity of ultrafiltration membranes. Therefore, the SCB-PSF ultrafiltration membranes displayed excellent antifouling performance (flux recovery ratio is 82.53%) and BSA rejection rates (94.77%). SCB-PSF also had high photocatalytic self-cleaning activity, indicating excellent application prospects in organic wastewater treatment .

Given the problems in sewage treatment and clean water production, this study developed a solar steam generating device. Such a developed device comprised a superhydrophobic photocatalytic layer and a polypyrrole photothermal layer. To be specific, the superhydrophobic photocatalysts were capable of selectively adsorbing surface organic solvents and photodegrading dissolved pollutants, while the polypyrrole photothermal layer had a function of absorbing light energy and forming an interfacial heating layer to avoid heat loss. To improve the photodegradation ability, the photocatalyst of Bi 2 MoO 6 was added, and its crystal structure and specific surface area were investigated specifically. The photocatalyst was supported on a fabric substrate to form a bulk material, thereby avoiding the defects of poor reuse of powder catalysts. After 8 cycles, the degradation efficiency remained higher than 98 %. In addition, the fabric exhibited an excellent mechanical stability, of which the average friction coefficient remains stable. Interestingly, after the sewage treatment, the fabric could act as the substrate of photothermal devices to ensure floating. The steam production efficiency was improved by the synergistic effect of the polypyrrole photothermal layer and the fabric.

Photocatalysts have offered a successful strategy for degrading organic pollutants, such as various dyes and antibiotics, in wastewater. In this study, the flower-like Bi 2 MoO 6 balls were impregnated on the zirconium-based MOFs (MOF-801) to construct the Bi 2 MoO 6 /MOF-801 heterojunction composite photocatalytic materials through a simple one-pot hydrothermal method. The systematically characterization of the as-synthesized composite materials was performed using various analytical techniques, including XRD, FTIR, SEM-EDS, N 2 adsorption⁃desorption testing, TG, XPS, UV-Vis DRS, PL, transient photocurrent, and EIS techniques, thereby confirming the successful impregnation of Bi 2 MoO 6 into MOF-801. The degradation effect of the Bi 2 MoO 6 /MOF-801 composites on rhodamine B (RhB) dye was investigated, along with the photocatalytic degradation mechanism. Results showed that 0.1-Bi 2 MoO 6 /MOF-801 has better degradation efficiency for RhB dye than that of pure Bi 2 MoO 6 and MOF-801 under visible light conditions, with a complete degradation efficiency of 98.1% achieved within 40 min. The boosted photocatalytic performance of the 0.1-Bi 2 MoO 6 /MOF-801 composite is attributed to their high specific surface area (529.2 m 2 /g) and mesoscale pore size (6.9 nm), wide visible spectral absorption, well-optimized band gap (2.81 eV), and the close contact of Bi 2 MoO 6 and MOF-801 ensuring efficient charge separation and suppressing the recombination of photogenerated electron-hole pairs. Visible-light driven photocatalysis of 0.1-Bi 2 MoO 6 /MOF-801 composite further confirmed superior degradation of MB, AO, CR, MO, and ARS dyes, reaching degradation efficiencies up to 99.7%. Moreover, the results of the free radical capture experiments confirmed that the holes ( h + ) and superoxide radicals (•O 2 − ), and electrons ( e − ) were the primary active substances during the degradation process, supporting the Z-scheme heterojunction charge transfer mechanism. This research study will point the direction for designing potential and affordable MOF-based heterojunction materials for the treatment of dye-contaminated wastewater. Graphical

Photocatalytic nitrogen fixation is a promising route for sustainable ammonia synthesis, yet its efficiency is often hampered by rapid charge recombination and insufficient N 2 adsorption. Herein, we report the fabrication of iodine-doped carbon quantum dots (ICQDs) modified Bi 2 MoO 6 (BMO) nanosheets via a hydrothermal method to address these challenges. The incorporation of ICQDs significantly increases the specific surface area and form a more porous composite structure with BMO that is conducive to adsorption, thereby facilitating N 2 adsorption. Consequently, the optimized ICQDs-BMO composite exhibits a remarkable ammonia production rate of 124.67 μmol g −1 h −1 , approximately 2.4-fold higher than that of pristine BMO. This substantial enhancement is attributed to the synergistic effects of improved charge separation and transfer efficiency, extended visible-light absorption, and increased oxygen vacancies induced by ICQDs. This work provides a viable strategy for designing high-performance photocatalysts by integrating iodine-doped carbon nanomaterials with semiconductors for efficient solar-to-ammonia conversion.

This study developed a series of yellow and orange pigments with enhanced near-infrared reflectivity. These pigments were prepared through high-temperature solid-state reaction, CeO 2 doping, and Bi 2 MoO 6 modification. The pigment samples exhibit Bi 2 MoO 6 related to the monoclinic crystal system, with no discernible peaks of oxide impurities. The pigments were transformed from white to yellow and orange by doping Ce ions, which have better color performance. The reflectance in the infrared spectrum and near-infrared solar reflectance of all pigment samples were found to be greater than 95 %. After 60 min of exposure to infrared radiation, the internal temperature difference between the Bi 1.88 Ce 0.12 MoO 6-δ painted iron house model and Bi 1.88 Ce 0.12 MoO 6-δ unpainted iron house model reached 8 °C. The color change of Bi 1.88 Ce 0.12 MoO 6-δ was minimal in acidic, alkaline, and high-temperature environments, thus confirming its excellent stability. These characteristics indicate that the synthesized Bi 1.88 Ce 0.12 MoO 6-δ pigment has considerable potential in energy saving and multifunctional coatings.

Ultrathin structures have gained more and more attention due to their large surface area and abundant reactive sites, which are beneficial for the improvement of performances. Herein, we report an ultrathin Bi 2 MoO 6 synthesized by a simple mannitol-assisted hydrothermal method for the first time. The as-synthesized ultrathin Bi 2 MoO 6 exhibits highly selective adsorption efficiency toward various positively charged organic dyes. Moreover, the ultrathin Bi 2 MoO 6 displays enhanced photocatalytic activity in comparison with pristine Bi 2 MoO 6 . Systematic photoelectrochemical measurements reveal that the higher separation efficiency of photogenerated carriers takes responsibility for the improved photocatalytic performance. This work provides a simple path for designing ultrathin nanoarchitectures and widening application for these ultrathin materials.
